““Education is presumed to nurture an appreciation of diversity: the more schooling, the greater the respect for works of literature and art, different cultures, and various types of music. Certainly, well-educated Americans see themselves as worldly, nuanced, and comfortable with difference. Education also should make us curious about—even eager to hear—different political points of view. But it doesn’t. The more educated Americans become—and the richer—the less likely they are to discuss politics with those who have different points of view.””
